Product Description

HearDefenders-DF are the first and only product to offer the flexibility of two levels of hearing protection and the ability to hook up to radio communications. Specifically designed to help the user hear critical sounds including speech, while filtering out loud and/or harmful impact sounds.

Size medium is best for most people. To choose the correct size based on the diameter of your ear canal (you may need assistance):

Small: 7-11mm

Medium: 10-14mm (similar to a AAA battery)

Large: 12-16mm (similar to a AA battery)

OSHA regulations state volume levels of 80 – 85 dB are safe for an eight hour period of time. If you are concerned about the volume at which you are using these plugs, please consult a hearing healthcare professional who can advise you about safety levels and appropriate filtering options.
